16-CHANNEL T1/E1/J1 SHORT-HAUL LINE INTERFACE UNIT

Transmit Diagnostic Pattern Detection
The transmit path has the ability to detect diagnostic patterns on the system side interface from the TPOS input
pin (Single Rail Mode Only). The LIU can detect an All Ones (SAIS), Loss of Signal (RLOS), or PRBS/QRSS
(SPRBS).
4.5.1
SLOS (System Loss of Signal)
The XRT83VSH316 supports both G.775 or ETSI-300-233 RLOS detection scheme.
In G.775 mode, LOS is declared when the received signal is less than 375mV for 32 consecutive pulse periods
(typical). The device clears LOS when the receive signal achieves 12.5% ones density with no more than 15
consecutive zeros in a 32 bit sliding window and the signal level exceeds 425mV (typical).
In ETSI-300-233 mode the device declares LOS when the input level drops below 375mV (typical) for more
than 2048 pulse periods (1msec).
The device exits LOS when the input signal exceeds 425mV (typical) and has transitions for more than 32
pulse periods with 12.5% ones density with no more than 15 consecutive zero’s in a 32 bit sliding window.
In T1 mode RLOS is declared when the received signal is less than 320mV for 175 consecutive pulse period
(typical). The device clears RLOS when the receive signal achieves 12.5% ones density with no more than 100
consecutive zeros in a 128 bit sliding window and the signal level exceeds 425mV (typical).
4.5.2
SYS_EXLOS (System Extended Loss of Signal)
By enabling the system extended loss of signal by programming the appropriate channel register, the digital
SLOS is extended to count 4,096 consecutive zeros before declaring SLOS in T1 and E1 mode. By default,
EXLOS is disabled and SLOS operates in normal mode.
4.5.3
SAIS (System Alarm Indication Signal)
The XRT83VSH316 adheres to the ITU-T G.775 specification for an all ones pattern. The alarm indication
signal is set to "1" if an all ones pattern (at least 99.9% ones density) is present for T, where T is 3ms to 75ms
in T1 mode. AIS will clear when the ones density is not met within the same time period T. In E1 mode, the
AIS is set to "1" if the incoming signal has 2 or less zeros in a 512-bit window. AIS will clear when the incoming
signal has 3 or more zeros in the 512-bit window.
